## About 

Project demonstrating obtaining a colored layer for an avalanche relief map using gdal.  

## Steps

`make download` - download high resolution DEM model (1m).  

`make slope` - calculate slopes with edges.  

`make paint` - coloring the layer.  

## Output

`mount_st_helens_usgs_1m_dem.tif` - DEM model (1m).  

`mount_st_helens_usgs_1m_dem_slopes.tif` - avalnches relief map.  

`mount_st_helens_usgs_1m_dem_slopes_painted.tif` - colored avalnches relief map.
